Specification of Letters Patent.

T0 all whom t may concern.'

Be it known that LJoHN KINoAm, a cit-izen of the Dominion of Canada,residing at Vancouver, in the Province of British Golumbia, Canada, haveinvented a new and useful Vater-Wheel-Gate Ring, of which the followingis a speciiication.

This invention relates to a means for controlling the flow of water tothe nozzles of a multiple jet impact water wheel and is designed tocontrol not only the passages to the nozzle vbut also the number ofnozzles through which the water is directed onto the vanes or buckets ofthe wheel while maintaining a balance in the disposition of the jets onopposite sides of the wheel.

The invention is fully described in the following specification,reference being made to the drawings by which it is accompanied, inwhich: 1

Figure 1 is a vertical section through the casing of a wheel rotatableon a vertical axis. Fig. 2, a horizontal section of the same, and Figs.3 and 4 are developments of the rotatable control rings. Fig. 5 is adetail top plan view illustrating the ring adjusting means. In thesedrawings 2 represents the circular casing or nozzle ring of the wheelfrom which the nozzles 3 which may be integral with or removably securedto the casing, inwardly project at an angle approximately tangential tothe path of the buckets or vanes of the wheel and 4 is the casing coverwhich has a bearing which with the footstep bearing, support the wheelshaft.

The outercircumference of the nozzle ring 2 is turned to receive a ring6 with a ring 7 tted on the outside of it, the ring 6 being rotatable onthe nozzle ring 2 and 7 on 6. Both the rings are provided with apertures8 and 9 corresponding in number and dimension and registering with thoseof the nozzle ring 2. In addition to the apertures 8 and 9 each of theserings is provided with supplementary apertures 10 and 11 the number ofwhich is any required fraction of the number of nozzles and equallydistributed around the ring, so that when either ring is rotated tobring its supplementary apertures into use they-will register withcertain of the apertures of the nozzle ring in the case of the innerring 6 and with the apertures 8 in the case of the outer ring 7.

The developments in Figs. 3 and 4 show clearly the relation of thesupplementary apertures to the full power apertures 8 and 9 of eachring. The drawing shows a twelve nozzlewheel and each ring 6 and 7 istherefore provided with twelve apertures 8 in one and twelve apertures 9in the other, which apertures will register with one another.

If the gate rings are designed to control the wheel by cutting out, sayone-third and one-half of its nozzles in use, then one of the rings, saythe inner one, is provided with eight supplementary apertures 10 whichapertures, in order to have them equally distributed, are arranged, seeFig. 3, in pairs interspaced between each alternate pair of theapertures 8.

The outerring 7 is provided with six supplementary apertures 11 whichare pitched around the ring, see Fig. 4, one between each alternate pairof the apertures 9. These rings 6 and 7 are independently rotatablethrough an arc of `movement sufficient to bring the supplementaryapertures to register with those of the nozzle ring by means of asegment of rack teeth 15 projecting upward from each ring, in the teethof which mesh those of separate pinions 16 mounted on spindles 17rotated by means of hand wheels 18. y

The water from the penstock or casing in which the wheel is placed willpass through all the nozzles 3 when both rings 6 and 7 have theirapertures 8 and 9 in register with those of the nozzle ring.

By rotating the inner ring 6 to bring the apertures 10 to register whileretaining the apertures 9 of the ring'7 in their original positionregistering with those 3 of the nozzle ring, water will be passed` toeight of the nozzles, or two-thirds of the whole number, or if the outerring is moved to registerk it-s supplement-ary apertures 11 while thering 6 has its full power apertures 8 in, register, the wheel will beserved through six, or one-half of its total nozzles. Again, if theinner ring 6 is moved to bring its supplementary apertures in registerand the outer ring 7 is moved to bring its supplementary apertures toregister, the outer ring will cut out half of the supplementaryapertures of the inner ring and the wheel will be served through fournozzles, or one-third of the total. Thus we have a range of control in atwelve nozzle wheel ranging through twelve, eight, six or four nozzles,and the circumference of the nozzle ring is so proportioned to thediameter of the nozzle inlets or the ring apertures that an interspaceoccurs between the apertures of the outer ring sufficient to cut off orclose the apertures. entirely' when the ring is.ro- .tated' to bring theinterspace over the aperture of the inner ring. Means is thus Vprovidedby which a wide range of control j over the water admitted to the wheelis lobtained for not only may the gates to each vnozzle ,be uniformlygraduated or cut ofi entirely but the number of jets which areby LettersPatent, is:

1. A means for controlling the admission of water to the jets of amultiple jet water wheel, said means comprising two rings one `rotatablyiitting over the jet inlets of the wheel casing and the other over thering yboth rings having through apertures corresponding in number andregisteringwith the jet inlets and with them and with one .another eachring having interplaced between the aforementionedaperturessupplementary apertures distributed around the rings the numberof the supplementary apertures in each being a different fraction of thenumber of jets and registering in pitch with certain of them and meansforv independently rotatin each ring.

2. Means for control ing the admission of water to the jets of amultiple jet waterl wheel, Vsaid means comprising a ring rotatablyfitting over the jet inlets of the wheel lcasing said ring havingapertures corresponding in number and pitch with the apertures of thejets so as to register with them and in the interspace between theseapertures other apertures in number less Ythan those jet apertures butregistering with certain of them, a second ring rotatably fitting on theaforementioned ring and provided with apertures registering with thosewhich correspond in number with the jet apertures and supplementaryapertures fractionally less in number than either the jet apertures orthe supplementary apertures of the first mentioned ring'and registeringwith certain of them and means for' independently rotating each ring.

3. Means for controlling the admission of water to the jets of amultiple jet water wheel, said means comprising two rings one `rotatablyfitting over the jet inlet of the wheel casing and the other over thering both rings having through apertures corresponding in numberfwiththe jet inlets and registering with them and with one another each ringhaving interplaced between the aforementioned apertures supplementaryapertures distributed around the rings the number of these supplementaryapertures inv each ring being a'v different fraction of the number ofjets and registering in pitch with certain of them, means forindependently rotating each ring said means comprising a segment of rackteeth projecting from the edges of the rings and separate pinions theteeth of which mesh with those of the rack segments and meansforindependently rota-ting the pinions.

4. A means for controlling the admission of water toV the jets of amultiple jet water wheel, said means comprising a ring rotatably fittingover the j et inlets of the wheel casing-said ring having aperturescorresponding in number and pitch with the apertures to the jets so asto register with them and in the interspace between these aperturesother apertures in number less than those jet apertures but registeringwith certain of them, a second ring rotatably fitting on theaforementioned ring and provided with apertures registering with thosewhich correspond in number with the jet apertures and supplementaryapertures fractionally less in number than either the jet apertures orvthe supplement-ary apertures of the first mentioned 'ring andregistering with certain of them, the circumference of the rings beingso proportioned to the vdiameter of the apertures that an interspace isprovided between the apertures which is slightly larger than theaperture and means for independently rotating each ring. v

In testimony whereof I have signed my name tovthis specication in thepresence of two subscribing witnesses.
